The Fermi Paradox is a question that stumps and fascinates scientists (and pretty much everyone else, let's be real.) The question, originally posed by Italian physicist Enrico Fermi, wonders at why there are theoretically so many habitable planets in the universe, but humanity has yet to make contact with any form of… »12/28/14 5:47pm 12/28/14 5:47pm

Before either Bill Nye or Carl Sagan were on television, Nye was a student in Sagan's astronomy class at Cornell. Here's Nye reminiscing about that class — and the advice Sagan gave him before he started his own show. »3/21/14 1:50pm 3/21/14 1:50pm

There are always consequences when engaging with the enemy. And when Bill Nye "The Science Guy" agreed to debate evolution vs. creationism with Creation Museum founder Ken Ham last month, he was considered to have won the debate, but he also brought a financial windfall to the museum that Ham describes — of course —… »3/03/14 12:20pm 3/03/14 12:20pm

When I was very young, science was incredible to me. I watched Bill Nye whenever I could, which was almost never—thanks, baby sister of yesteryear. At one point I heard you could watch him on the World Wide Web, so I begged my Dad to let me try. We sat waiting while our 56K modem struggled to load a full ten minutes… »2/07/14 2:46pm 2/07/14 2:46pm

At 7:00 pm EST, the fabled debate between Bill "The Science Guy" Nye and creationist Ken Ham will go down at the Creation Museum in Petersburg, Kentucky. Seeing as neither of them believe in each other's view in the slightest, this should be insane — and you can watch the madness as it unfolds live, right here! »2/04/14 3:45pm 2/04/14 3:45pm

Not that you needed any additional reasons to love famed astrophysicst Neil deGrasse Tyson and educator/comedian/TV host extraordinaire Bill Nye, but just in case: Here's Neil calling his buddy Bill while onstage at Florida State University (the sounds gets better at 1:40). Do you think they have sleepovers together?… »11/07/13 10:20am 11/07/13 10:20am

Bill Nye, who tore 80% of his quadricep last week, was told not to participate in last night's Dancing with the Stars. But he did anyway, performing a Daft Punk-inspired robot dance with Tyne Stecklein that required him to move his injured leg as little as possible. The duo won't be returning, but they left the stage… »10/01/13 6:20am 10/01/13 6:20am

As prophesied, Bill Nye the Science Guy had his inaugural dance on Dancing with the Stars, a chacha set to — what else? — the Weird Science theme, inside a mad scientist's laboratory. Nye was somehow surprisingly good but totally awkward at the same time, but he didn't get booted off, so the experiment will continue… »9/17/13 8:40am 9/17/13 8:40am

It's always wonderful to see children's television staffers pay care and attention to the important details of their shows.

Bill Nye teamed up with Mitchell Moffit and Gregory Brown of AsapSCIENCE to address one of the most pressing not-if-but-when questions in recent memory: how do we stop a major asteroid from colliding with Earth? »7/24/13 7:20am 7/24/13 7:20am

It's a question long been pondered by nerds the world over. If Superman's hair is as super-strong as the rest of him (and it is, a single hair can hold up a 1-ton weight ), how does he manage to shave! io9 is happy to exclusively present Bill Nye, The Science Guy's theory! »5/28/13 8:40am 5/28/13 8:40am

When Honey Booboo and other godawful reality shows clog the airwaves, there's only four people you can call. Carl Sagan. Mr. Rogers. Bill Nye the Science Guy. Bob Ross. Together, they are the PBS Avengers, and this world would be a better place if this video were real. »5/01/13 2:40pm 5/01/13 2:40pm

For 14 years now, the American Museum of Natural History has hosted the Isaac Asimov Memorial Debate – an annual meeting of scientific and philosophical minds, held in honor of one of modern history's most formidable intellects. The debates are always fantastic, but this year's topic – the existence of nothing –… »4/25/13 10:30am 4/25/13 10:30am
